CANNING APPARATUS.

Specification of Letters Patent. Patented Jan. 16, 1917.

'Application filed January 17, 1916. Serial No. 72,573.

To all whom it may concern 1 Be it known that I, EDWARD'M. HARP, a citizen of. the United States, residing at Dublin, in the county of Laurens and State of Georgia, have invented certain new and useful Improvements in Canning Apparatus; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in an apparatus for canningvfruits and vegetables andlike purposes and is more particularly designed for usef'in ahou'sehold.

The primaryobject of the invention is to provide a device of this character which can be readily taken apart and cleaned or repaired. l i Another object of the invention is. to provide a device which is light, durable, simple in construction, cheap to manufacture, easy to operate, and well adapted to the purpose for which it is designed.

lVith theseand other objects in view the invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the accompanying drawings in which similar reference numerals indicate like parts throughout the several views; Figure l is a perspective view of a device constructed in accordance with this invention; Fig.

2 is a vertical longitudinal sectional view of the same; Figs. 3 and 4 are horizontal sectional views taken on the lines 33 and 4& of Fig. 2; Fig. 5 is a transverse sectional View taken on the line 55 of Fig.

2; and, Fig. 6 isa perspective view of one of' the tray hangers.

Referring more particularly to the drawings, 1 represents the water tank of this improved canning apparatus, here shown as being rectangular in configuration and made walls of said tank, the latter being provided.

with openings adjacent the ends of said pipe 2. This pipe 2 may be of any desired shape but is here shown as being square shaped in cross section, the sides and bottom thereof being parallel with and spaced equal distances from the sides and bottom respectively of the tank. Hinged to the front end of the tank 1 is a door 3, the latter being disposed over the front end of the pipe 2. This door 3 may if desired be provided with a suitable ventilator. A removable lid 4; covers the top of the tank 1 to prevent dust and dirt from collecting within the interior thereof and may also be used during the cooking process.

WVithin thepipe 2 is afire-box 5 which consists of a pipe of square shape in cross section and having its front end open and.

disposed adjacent the door 3. The rear end of the fire-box 5 is closed and extends beyond the plane of the rear end of the tank 1, the upper side of the extended rear end of the firebox having an opening 6 therein to the edge of which is secured a smoke pipe collar 7 This fire-box '5 fits loosely within the pipe 2 and may be readily withdrawn from the same.

, Extending upwardly and rearwardly from the rear end of the fire-box 5 is a smoke pipe 8, the lower end. of whichhas removable engagement with the collar 7. This smoke pipe 7 is slidably engaged withina guide ring 9 carried at oneend of a bracket 10, the latter being secured at its other end in any suitable manner to the rear end of the tank 1 preferably near the upper edge thereof. This bracket and ring, in addition to supporting the smoke pipe, provide a very simple and eflicient means for preventing withdrawal of the fire box. With the parts assembled as above and it is desired to remove the fire-box, the smoke pipe 8 is raised a sufficient amount to disengage the lower end thereof from the collar 7 whereupon the fire box' may be readily withdrawn. r

Extending transversely across the interior of the tank 1 are can supporting bars 11, the ends of which are bent upwardly and se cured to the sides of said tank 1 in any suitable manner. The ends of the tank 1 are provided near their upper edges with inwardly extending pins 12, the purpose of which will be hereinafter described.

7 In operation a suflicient quantity of water is placed in the tankrl and brought to the desired temperature by the heat from a fire which is made in the fire-box 5. The air enters the fire-box at the front end thereof and the smoke and products of combustion pass out through the smoke pipe 8. Owing to the fact that the water completely surrounds the pipe 2 no heat is wasted and very little time is required to heat the water. During the cooking process the lid 4 is removed and the cans containing the fruit or vegetables to be canned are placed in rectangular trays 13 and lowered into the water, the lower tray resting upon the bars 11. The handles 14 at the ends of the upper tray 13 are engaged with hooks 15 which are carried at the lower ends of a pair of hanger members 16, the latter being provided with a plurality of apertures 17 for engagement with the pins 12. Bythis arrangement it may be seen that the upper tray may be lowered to any desired depth. The bottoms of these trays 13 are provided with apertureslS to allow proper circulation of the water in the tank as will be readily understood. In the drawings two trays are shown, but it is obvious that as many as desired maybe used without departing from thescope of this invention.

From the foregoing it may be seen that the objects of the invention have been conveniently carriedout, the device illustrated being of simple construction, cheap to manufacture, easy to operate and the parts of which are readily removablefor cleaning or repairing.

Although the device is designed particularly for domestic use for canning, it is not to be limited to that use alone, as it is ob- Copies of this patent niay be obtained for vious that it may be used for boiling clothes, and other similar purposes.

As various changes in form and proportion may be resorted to without departing from the spirit of this invention, I do not wish to be limited to the construct-ion herein shown and described other than that set forth in the appended claim.

I claim as my invention:

A canning apparatus comprising a cooking tank, a guideway extending through said tank and opening through the front and rear sides thereof, a door closing the front end of said guideway, a fire box inserted removably into said guideway through the rearend thereof, said fire box having an open front end and a closed rear end, the lat.-

V ter projecting rearwardly beyond the tank and having an upstanding rigid collar, a rigid loop secured to the rear side of the tank and spaced above said collar, and a smoke pipe received slidably in said loop and telescoping with said collar, whereby said pipe normally holds the firebox against shifting in the guideway and whereby upward sliding of said pipe will permit removal of said fire box.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
